Flat roofs need to be built and repaired with care, especially in wet and windy parts of Devon. At Terrabase Roofing, we install and repair flat roofs for homes, extensions, garages, porches and commercial buildings. With over 20 years of experience, we know how to create a flat roof that’s neat, watertight and made to last.
We provide flat roofing across Devon, including new flat roof installation, flat roof repairs, replacement flat roofs and maintenance work. Whether your existing roof is leaking, blistering, cracked or simply reaching the end of its life, we’ll inspect it properly and explain the best option.
We work with practical flat roofing systems suited to different properties and budgets, including GRP flat roofing where appropriate. The right system depends on the building, the roof size, drainage, access and how exposed the property is.
Customers choose Terrabase Roofing because we take the preparation seriously. A flat roof needs the right falls, detailing, edging and finish. If those details are missed, problems can appear quickly, especially after heavy rain.
We start by checking the existing roof structure and identifying any weak areas. From there, we prepare the surface, install the correct roofing system and finish the edges, outlets and joins carefully so the roof can shed water properly.


Our flat roofing service is suitable for homeowners, landlords, local businesses and property managers across Devon. We work on flat roofs for single-storey extensions, garages, outbuildings, dormers, balconies, porches and commercial units.
Flat roofs often show warning signs before they fail completely. You may notice damp patches inside, water sitting on the surface, bubbling, splits, loose trims or staining around the ceiling. Sometimes the problem is obvious. Other times, the leak has travelled before appearing indoors, which is why a proper inspection is important.
Across Devon, flat roofs have to deal with regular rainfall, changing temperatures and strong winds in more exposed locations. Properties near the coast around Torquay, Exmouth, Sidmouth and Bideford can face particularly harsh weather, while older homes and extensions in places like Exeter, Plymouth, Newton Abbot and Barnstaple may have ageing flat roof coverings that are no longer performing as they should.
We carry out flat roof repairs where the existing roof is still in reasonable condition. This can include fixing splits, sealing problem areas, repairing damaged edges or dealing with leaks around outlets and upstands. If the roof has widespread damage or has been patched several times already, a replacement may be the better long-term choice.
For new flat roof installation in Devon, we’ll talk through the available options and explain what would suit the property. GRP flat roofing is a popular choice for many customers because it creates a seamless, hard-wearing finish when installed correctly. Whatever system is used, our focus is always on good preparation, clean detailing and reliable weather protection.
We visit the property, inspect the flat roof and look for signs of damage, poor drainage or weak detailing.
Once we understand the condition of the roof, we’ll explain whether repair or replacement is the better option.
We provide a clear quote for the work, including the materials and preparation required.
The roof area is prepared properly before work begins. This may involve removing old coverings, checking the deck and dealing with any damaged areas.
Before leaving, we check the finish, edges and drainage points to make sure the roof has been completed properly.
